After many hours of searching, I have finally learned that the "transparent black-white vision" in my blind areas are called "blindsight". Blindsight is not sight at all. Apparently my brain is just trying to use a non visual pathway to route information. But this visual information is not being processed correctly.
This is not hopeful sign that I had wanted. It was all just too good to be true.

: On March 7, 2000, I underwent a quintuple coronary artery bypass operation. My heart unexpectely stopped beating for several minutes during this operation, but I appeared to be fine when I awoke. On March 10, I was released from the hospital.
: On March 12, on a Sunday night, I became confused while doing a simple task. I saw a "huge curved screen" about 10 inches in front of my eyes. This "screen" reached all the way to the "top" and all the way to the "bottom." This screen also reached all the way to the right and all the way to the left. In the center of this screen was a narrow very bright white light that reached almost all the way to the "top" and almost all the way to the "bottom." The top and bottom of this white light were jagged. The width of this white light constantly changed slightly. The jagged parts on the top and bottom were constantly changing position. To the right of this white light was a great deal of blackness. To the left of this white light I could see, but my vision was dim. I am surprised that I did not become alarmed. I did not call for help. I went to bed.
: The next day, Monday, March 13, I found that I had lost the right 1/2 of my central vision and I had lost all the vision on my right. I could not read well. I saw two doctors on an emergency basis. 20 hours after my stroke I was admitted to a hospital.
: On March 15, I regained some of my lost field of vision.
: On March 19, I was again released from the hospital.
: On March 27, I had a TEE (transesophageal echocardiogram) and when I awoke I found that I had regained some more of my lost field of vision.
: I spent much of April, May, and June relearning to read. I started with children's books. I can now read any book in the library.
: On August 28, I regained additional field of vision. In addition, I could now "see" where I am still blind. It is a "transparent black-white vision" where I can see movement. Here I can neither clearly see shapes nor can I see color.
: Today, September 18, 6 months and 6 days after my stroke, I have all of my central vision, and I have 3 of my 4 quadrants of vision. I now can see in about 1/2 of the other quadrant of my vision, my upper right. In the 1/2 of my upper right field of vision where I have no vision, about 3/4 of this area has this "transparent black-white vision."
: My questions are: What is the name of this "transparent black-white vision"? Do these changes make it more likely that further recovery will occur? What, if anything, can I do to make further recovery more likely?
